A general compliment is no issue.
That's not what's happened with prawn, particular posts have been singled out for pointed praise, the inference being that only a slither of his content is worthy of merit and an exception to the rest.
How would you have felt if the customer that called you a smart man had been in your shop and spoke to you hundreds of times then one day finally said something like 'you can be a smart man sometimes', puts a slightly different slant on it no?
I don't praise every comment I agree with, or find value in - that would be a full-time job. I also try not to hurl personal insults at someone who posts something I find wrong. Everyone on here posts ideas with merit, together with thoughts that others might find less worthy. When the latter happens is it really that bad to say that you find other comments more praiseworthy?
You're a smart man, but I disagree with you on this point.
On second thoughts, I am sure we agree. Critique the comment, not the person making it. It's just that sometimes one gets mistaken for the other.
